RAB Lighting SWISHAIR LED Air Handling Troffer — 2x2 & 2x4, Selectable Wattage & CCT, 120-277V, White

The RAB Lighting SWISHAIR is a slim, high-efficiency LED air handling troffer engineered for commercial interiors that require integrated HVAC ventilation and premium-quality illumination in a single ceiling fixture. Available in 2x2 (SWISHAIR2X2) and 2x4 (SWISHAIR2X4) sizes, and with or without air return vents, all configurations feature field-adjustable wattage, selectable 3500K/4000K/5000K CCT, and a universal 120-277V input. The 2x2 delivers up to 4,702 lumens at 35W; the 2x4 delivers up to 6,047 lumens at 44W — both at up to 140 LPW efficacy with 82-84 CRI. A 0-10V dimming driver and 2kV surge protection are standard across all models.

RAB SWISHAIR Features

• Air Handling Integration: Specialized housing slots allow the fixture to serve as an HVAC air return, eliminating separate ceiling vents and reducing ceiling clutter in commercial spaces.
• Two Size Options: Choose 2x2 (23.75” × 23.75”) or 2x4 (47.75” × 23.75”) to fit standard T-bar drop ceiling grids.
• With or Without Vents: Select the air-return vent configuration based on your HVAC layout — both options share identical electrical and optical performance.
• Field-Adjustable Wattage: 2x2 offers 18W/26W/35W; 2x4 offers 26W/35W/44W — set on-site to match illumination and energy targets.
• Selectable CCT: Field-adjustable 3500K, 4000K, and 5000K color temperatures via on-fixture switch for precise ambiance control.
• High Efficacy: Up to 140 LPW with 82-84 CRI and a uniform PMMA diffuser lens for glare-free illumination.
• 0-10V Dimming: Dims to 10% for advanced energy management and compatibility with commercial lighting control systems.
• Universal Voltage: 120-277V input compatible with standard commercial electrical systems.
• 2kV Surge Protection: Guards internal components against facility power transients.
• UL Listed — Damp Location: Suitable for commercial restrooms, locker rooms, and humid interior spaces.
• 100,000-Hour Lifespan: L70-rated LED life with a 5-year warranty minimizes maintenance in commercial installations.
• Cold-Rolled Steel Housing: Durable white finish integrates cleanly into standard T-bar drop ceiling systems.

Dual Selectable Technology

All SWISHAIR configurations feature field-accessible wattage and CCT selector switches, allowing installers to dial in the exact output and color temperature on-site without additional tools or rewiring.

Typical Applications

• Corporate offices and open workspaces.
• Healthcare facilities and medical corridors.
• Educational institutions and classrooms.
• Retail showrooms and hospitality interiors.
• Government buildings and libraries.
• Commercial restrooms and damp interior spaces.

Performance & Light Output

Both SWISHAIR configurations deliver up to 140 LPW efficacy with 82-84 CRI across all wattage settings. The PMMA diffuser lens provides uniform, glare-free illumination without harsh shadows — ideal for task-intensive commercial environments. The 100,000-hour L70 lifespan dramatically reduces re-lamping and maintenance costs versus legacy fluorescent troffers.

Electrical & Controls

Each model is powered by a constant current driver operating on 120-277V AC. All configurations include a 0-10V dimming interface (dims to 10%) for compatibility with commercial lighting control systems and occupancy-based energy management. Built-in 2kV surge protection guards internal components against facility power transients.

Construction & Durability

The cold-rolled steel housing is finished in white and features a slim 1.44” profile that integrates cleanly into standard 2x2 or 2x4 T-bar drop ceiling grids. Air-return vent models include specialized housing slots that allow the fixture to serve as an HVAC return, eliminating the need for separate ceiling vent tiles. UL Listed for damp locations, the fixture operates reliably in ambient temperatures from -4°F to 104°F (-20°C to 40°C).

Installation & Mounting

Designed for recessed installation in standard T-bar drop ceiling systems. T-grid clips are included for secure mounting. The fixture integrates seamlessly with existing HVAC ductwork layouts — the air-return vent models eliminate the need for separate ceiling vent tiles, providing a clean, uncluttered architectural appearance. Field-accessible wattage and CCT selector switches allow on-site adjustment during commissioning.
